- These photos show once again emissions which extend across
the entire wingspan, and consequently they can not emanate solely from
the engines of the aircraft, which in this case are rear mounted (tentatively
identified as a MD80, a derivative of the originally identified McDonnell
Douglas DC9; further identification assistance has been provided by a pilot
of 10000 hrs military, civilian, and commercial time).
-
- The reader will also note again a distinct pinkish coloration
in the emissions, which is even more visible in the original photos. These
photographs are the fourth case presented of wingtip-to-wingtip aerial
spraying in the United States, and as captured on film by three independent
photographers in separate locations. These photographs were taken with
a lens with an effective focal length of 1200mm (4 feet), as described
on the web page "How to Photograph a Chemplane" on www.carnicom.com.
-
- Upon additional questioning with the photographer, the
trails shown in these photographs were designated as persistent, they extended
from horizon to horizon (east to west), and they resulted in additional
cloud cover in combination with the heavy activity over Santa Fe on Nov
30 1999. Insufficient data was collected by the photographer to allow a
photogrammetric estimate of the altitude of the aircraft."
